Disable
When this parameter is enabled all data transmitted to host computer or Formula
terminal is completed by Block Check Characters that carry out a transmission check.
If transmission is successful the receiving instrument sends an ACK character. By
contrast if transmission occurs with a wrong checksum, the receiving instrument
replies with a NAK character.
It is advisable to always define the Block Check Characters when connecting host
computer to Formula terminal because this is the only way to check that data is not
lost or corrupted

For example, set command data to "9" to obtain a Delay of 0.45 seconds:
SERIAL COMMAND
0 = 30

1 = 31
